Getting IMAGE TEXTURE from iterated Material from iterated object

Oh I see…
The little “shield” icon?
See the setup I have now, is 20+ planes (2mx2m each) with the same material copied over and over as unique material makes, each with their own unique image texture already.

Replacing their image textures works fine now.

Thing is, I want to have the scene habe just ONE object/material/texture, then clone it however times users need, and use code to iterate the new materials and their textures add unique, (as I already have them, but just generated on the fly).

I have a previous version that does ALL of this, except making the copied(cloned) image texture be new and unique, ready to be replaced with unique image.

Current version works fine, but I’m trying to make it more dynamic and optimized.

I can rename the new objects and materials… But…
Any way to code the unique iteration of the cloned materials image texture?

That would be rad!
